Release Notes: This release is focused on performance and stability, and is very smooth, fast, and stable. Existing features (like navigation, code generation, and roundtrip) have been rounded off, and the new user interface (new look and feel, zoom, bird's eye view) is finished. You can now zoom and pan in the bird view, the most recent diagrams are accessible through tabs, there is a write-ahead feature for selection boxes. Poseidon now saves conforming to XMI 1.2 and UML 1.4.
Release Notes: The focus of this release is stability and usability. The most obvious change is the new front end design. It has new icons, good handling, and well designed navigation. The new zoom and a bird-eye overview also add usability.
Release Notes: Improvements to the sequence diagram, the navigation tree, and printing.
